UniFi Access vs. Legacy Keycard Systems: What to Know Before You Retrofit

Most commercial keycard systems were sold a decade or more ago on proprietary controllers, with per-door licensing, a clunky on-site server, and a dealer you have to call (and pay) for every change. When an employee leaves, re-badging is a chore. When a controller dies, replacement parts are expensive and slow.

Worse, many older systems have no real audit trail and no remote management. If you want to know who opened the back door at 9 p.m., you may not be able to find out.

UniFi Access runs on the same UniFi console as your cameras and network, so there's one platform and no per-door software license. Credentials can be NFC cards, Bluetooth, mobile, Apple Wallet, or a PIN — you choose per door and per group.

Every unlock is logged with the credential, door, and timestamp. You can schedule access by person and time of day, revoke a credential instantly from your phone, and unlock remotely for a delivery or contractor.

The good news: you usually don't replace your doors. A typical retrofit reuses the opening and adds a UniFi Access Door Hub (the controller), a reader, a locking device (electric strike or maglock), a door-position sensor, and a request-to-exit device. Power runs over PoE from a UniFi switch.

Budget roughly $2,400 per door installed for a standard retrofit, including hardware and labor. Gates, intercoms, and elevators price separately. We survey every opening first, because existing wiring and hardware change the scope.

Access control is regulated as security work in all three states we serve — through Tennessee's Alarm Systems Contractors Board, Mississippi's State Board of Contractors alarm/access classification, and the Arkansas State Police. It's worth confirming any installer is working within the right framework for your state.
